What are plastics?
“Plastics are non-biodegradable, synthetic polymers derived primarily from petro-fossil feedstock and made-up of long chain hydrocarbons with additives and can be moulded into finished products (excluding compostable plastic or polymer confirming IS/ISO 17088:2008). These polymers are broken in presence of suitable catalyst, into monomers such as ethylene, propylene, vinyl, styrene and benzene. These monomers are then chemically polymerized into different categories of plastics.
Plastic products have become an integral part in our daily life as a basic need. It produced on a massive scale worldwide and its production crosses the 150 million tonnes per year globally. In India approximately 8 Million tonnes plastic products are consumed every year (2008). Its broad range of application in films, wrapping materials, shopping and garbage bags, fluid containers, clothing, toys, household and industrial products, and building materials. It is a fact that plastics will never degrade and remains on landscape for several years. Mostly, plastics are recyclable but recycled products are more hazardous to the environment than the virgin products. The recycling of a virgin plastic material can be done 2-3 time only, because after every recycling, the plastic material is deteriorated due to thermal pressure. Considering, 70% of plastic consumption is converted as waste, approximately 5.6 million tons per annum (TPA) plastic waste is generated in country, which equals to 15342 tons per day (TPD).
Some Recyclable Plastics (Thermoplastics): PET, HDPE, LDPE, PP, PVC, PS, etc.
Non-Recyclable Plastics (Thermoset & others): Multilayer & Laminated Plastics, PUF, Bakelite, Polycarbonate, Melamine, Nylon etc.
WAY FORWARD FOR ACTIVE MEASURES:
A) Setting-up of systematic mechanism for plastic waste collection, segregation and disposal;
B) Recycling of plastic waste in an environmental friendly manner
C) Closure of industries in non-conforming areas
D) Utilization of plastic waste in road construction (Polymer-coating over stone aggregate);
E) Co-processing of plastic waste in cement kiln;.
F) Widespread mass awareness programme on use of plastic packaging, and its impact on environment, on littering;
G) Extended Producer Responsibility (EPR) or Corporate Social Responsibility (CSR) in management of plastic waste;
H) Use of bags made from alternate materials i.e. biodegradable and compostable films, jute cloth, paper etc.
Have a mantra for using Plastics: RECYCLE, REUSE, REDUCE......!!!!
